摘要
We demonstrate low-temperature high-density chip-stack interconnection using compliant bump. Low temperature chip stacking was carried out by two methods; (1) plasma cleaning of compliant bumps, (2) mechanical caulking using compliant bump and doughnut-shaped electrode. The latter method is very effective in realizing chip stacking even at room temperature.
